Featured Case Studies

A refinery wanted to ensure that pressure relief capacity was adequate for the loss of liquid seal scenario in a high-pressure separator (2,000 psig). Also, they were concerned about the pressure waves that would occur in the high-pressure separator’s outlet lines on rapid closing of the isolation valves.

The chemical company of a large integrated energy company was developing a corporate standard for LOPA, which incorporated a risk ranking matrix. The company was interested in obtaining an independent review of the design of the risk matrix, and in benchmarking the underlying risk tolerability criteria with generally accepted industry norms.

A large Canadian refinery is performing risk assessments to identify personnel, environmental, and operational hazards. This work is being done on a planned schedule with a different unit being reviewed annually. The challenge was to use Process Hazard Analysis (PHA) methodologies that provide an effective analysis appropriate to the unit to be studied and the potential hazards.

A large oil refinery with a very complex flare network had become so complex that the tools the refinery was using to evaluate the flows through the flare network could not adequately model the system. Management no longer had confidence that their model results reflected the actual network performance and therefore, could not be sure the system would perform properly in the event of a global relief scenario at the facility.
